摘要:
A method for differentiating between a blood vessel bifurcation and a bleeding blood vessel in an ultrasound volume includes performing vessel segmentation on the ultrasound volume, calculating vessel centerlines for the segmented vessels, automatically detecting a bifurcation candidate using the calculated vessel centerlines, placing a first marker at a predetermined distance before the detected bifurcation candidate, placing a second marker at a predetermined distance after the bifurcation candidate, placing a third marker at a predetermined distance alone a potential vessel branch of the bifurcation candidate, acquiring spectral Doppler waveform data at each of the three markers, and comparing the acquired spectral Doppler waveform data for each of the three markers to determine whether the bifurcation candidate is a point of internal bleeding.
